glMultiDrawArrays - render multiple sets of primitives from array data

C Specification

voidglMultiDrawArrays(GLenummode,constGLint*first,constGLsizei*count,GLsizeidrawcount);

Description

glMultiDrawArrays specifies multiple sets of geometric primitives with very few subroutine calls. Instead
       of calling a GL procedure to pass each individual vertex, normal, texture coordinate, edge flag, or
       color, you can prespecify separate arrays of vertices, normals, and colors and use them to construct a
       sequence of primitives with a single call to glMultiDrawArrays.

       glMultiDrawArrays behaves identically to glDrawArrays() except that drawcount separate ranges of elements
       are specified instead.

       When glMultiDrawArrays is called, it uses count sequential elements from each enabled array to construct
       a sequence of geometric primitives, beginning with element first.  mode specifies what kind of primitives
       are constructed, and how the array elements construct those primitives.

       Vertex attributes that are modified by glMultiDrawArrays have an unspecified value after
       glMultiDrawArrays returns. Attributes that aren't modified remain well defined.

Errors

GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if drawcount is negative.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array and the
       buffer object's data store is currently mapped.

Name

Notes

GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are
       available only if the GL version is 3.2 or greater.

Parameters

mode
           Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP,
           GL_LINE_LOOP, GL_LINES, GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP,
           GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY, GL_TRIANGLES_ADJACENCY and GL_PATCHES are
           accepted.

       first
           Points to an array of starting indices in the enabled arrays.

       count
           Points to an array of the number of indices to be rendered.

       drawcount
           Specifies the size of the first and count
